ArrayRef< TemplateArgument > FunctionTemplateDecl::getInjectedTemplateArgs ( )

Retrieve the "injected" template arguments that correspond to the template parameters of this function template.

Although the C++ standard has no notion of the "injected" template arguments for a function template, the notion is convenient when we need to perform substitutions inside the definition of a function template.
